Re: Changed trans fluid in my TH400 and now it wants to slip and not get into gear.
Did you check the fluid with it level, running, and in park? I see you made mention of neutral but not park. I don’t think you’d loose forward and reverse both because of clean fluid, and definitely not right away on start up. I could see maybe after a few hundred miles of the clean fluid circulating thru the system but not immediately on start up. TH400’s are tough as nails. I bet it’s still low on fluid.
